目的

探讨原发性高血压患者脂蛋白相关磷脂酶A2(Lp-PLA2)与动态动脉硬化指数(AASI)的关系。

方法

选取2018年10月至2019年10月在徐州市中心医院住院治疗的原发性高血压患者178例,通过24 h动态血压监测计算AASI,根据AASI中位数将患者分为<中位数组(低AASI组)和≥中位数组(高AASI组)各89例,采用t检验比较2组间年龄、体质量指数、收缩压、舒张压、空腹血糖、三酰甘油、总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、估算的肾小球滤过率(eGFR)、尿酸和AASI的差异,采用χ2检验比较2组间性别、吸烟史、糖尿病病史的差异,采用秩和检验比较2组间Lp-PLA2的差异。采用Spearman相关分析评估所有患者Lp-PLA2与AASI的相关性,并采用多因素线性回归分析分析患者AASI的影响因素。

结果

高AASI组与低AASI组患者年龄[(67.87±14.23)岁vs(55.65±14.59)岁]、收缩压[(136.96±16.23)mmHg vs(128.35±14.23)mmHg,1 mmHg=0.133 kPa]、空腹血糖[(5.95±2.26)mmol/L vs(5.36±0.82)mmol/L]、Lp-PLA2[127(100,169)ng/ml vs 103(86,150)ng/ml]比较均高于低AASI组,高AASI组与低AASI组患者舒张压[(72.26±12.87)mmHg vs (77.30±10.49)mmHg]、eGFR[(92.49±18.66)ml/(min?1.73 m2vs(106.90±15.83)ml/(min?1.73 m2)]比较均低于低AASI组,且差异均具有统计学意义(t=-5.654,P<0.001;t=-3.762,P<0.001;t=-2.296,P=0.024;Z=-2.470,P=0.014;t=2.867,P=0.005;t=5.553,P<0.001)。Spearman相关分析显示患者Lp-PLA2与AASI呈正相关(r=0.237,P=0.001)。多因素线性回归分析表明患者收缩压(β=0.431,P<0.001)、舒张压(β=-0.371,P<0.001)、空腹血糖(β=0.160,P=0.013)、Lp-PLA2(β=0.152,P=0.022)水平是AASI的独立危险因素。

结论

原发性高血压患者Lp-PLA2与AASI存在正相关的关系。

Objective

To investigate the relationship between lipoprotein-associated phospholipase A2 (Lp-PLA2) and ambulatory arterial stiffness index (AASI) in patients with essential hypertension.

Methods

A total of 178 patients with essential hypertension hospitalized at Xuzhou Central Hospital from October 2018 to October 2019 were enrolled. AASI was calculated through 24-hour ambulatory blood pressure monitoring. According to the median value of AASI, the patients were divided to either a low AASI group (less than the AASI median; n=89) or a high AASI group (equal to or above the AASI median; n=89). Differences of age, gender, body mass index, smoking history, diabetes history, systolic blood pressure, diastolic blood pressure, fasting blood glucose, triglyceride (TG), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), estimated glomerular filtration rate (eGFR), uric acid, and Lp-PLA2 levels between the two groups were evaluated. The correlation between Lp-PLA2 and AASI was assessed. Multivariate linear regression analysis was performed to analyze the association of Lp-PLA2 and clinical data with AASI.

Results

Compared with the low AASI group, age [(67.87±14.23) years vs (55.65±14.59) years], systolic blood pressure [(136.96±16.23) mmHg vs (128.35±14.23) mmHg], fasting blood glucose [(5.95±2.26) mmol/L vs (5.36±0.82) mmol/L], and Lp-PLA2 [127 (100, 169) ng/ml vs 103 (86, 150) ng/ml] were significantly higher, and diastolic blood pressure [(72.26±12.87) mmHg vs (77.30±10.49) mmHg] and eGFR [(92.49±18.66) ml/(min?1.73 m2) vs (106.90±15.83) ml/(min?1.73 m2)] were significantly lower in the high AASI group (t=-5.654, P<0.001; t=-3.762, P<0.001; t=-2.296, P=0.024; Z=-2.470, P=0.014; t=2.867, P=0.005; t=5.553, P<0.001). Spearman correlation analysis showed a positive correlation between Lp-PLA2 and AASI (r=0.237, P<0.001). Multivariate linear regression analysis showed that systolic blood pressure (β=0.431, P<0.001), diastolic blood pressure (β=-0.371, P<0.001), fasting blood glucose (β=0.160, P=0.013), and Lp-PLA2 (β=0.152, P=0.022) were independent risk factors for AASI.

Conclusion

There is a positive correlation between Lp-PLA2 and AASI in patients with essential hypertension.
